CAMERA.

Spcification of Letters Patent.

Patented Aug. 19, 1919.

Appiioatonyled October 22, 1917. Serial No. 197,978.

To all whom 'it may concern yBe it known tha/EFI, SIGMUND H. GALL- MEIER, a subject of the Emperor of Gerresiding at Rochester, in the county invented certain new and useful Improvements in Cameras, of which the following is a specification. p

The object of this invention is to provide a new andimproved form of focusing film camera. This and other objects of the 'invention will be illustrated in the drawings, described in the specification and pointed out in the claims at the end thereof.

In the drawings,

Figure 1 represents a perspective view of a camera embodying my invention, part of the camera being broken away.

FigcQ is a sectional view through the friction brake which prevents the winding spool from lturning in the reverse direction, the

section being taken on the line 2*-22 of Fig. 1.

In the drawings, like numeral references indicate like parts. In the drawings, 1 indicates the body of the camera, having a bed plate 2 pivotally mounted in the `front thereof. In the camera are provided a-bellows 3 and a lens front el mounted to move on a track or runway/'5, all of which areJ is wound up by the stud as it is rotated when the film is drawn forward to the spool 7 after successive exposures. This spring when permittedto uncoil ,willrotate the spool 6 in the reverse direction and will cause the film'to .be rewound on the spool y6 as often as may he desired in the manipulation of the camera.

A wire 11 is provided which is normally fastened to and wound on the spool 7. This wire is connected to the film 10 after the spool 6 has been loaded-into the camera andby means thereof the film and its paper covering are drawn forward to the spool'7 and. wound thereon.

Immediately back of the rear end of the `bellows is provided the opening 12 in the which normally close or partially these doors 1s a the light Vwhich passes through the lens front will fall without .interference on the red Celluloid back 13, which back and the picture thereon can be inspected by the operator from behind the camera who can move the lens front'to secure the correct focus. To draw the lm and its paper out of the road the spring 9 is'utilized. As the film is wound forward onthe spool 7 the spring 9 is wound up, and it always has the tend- ,ency to tur-n the spool 6 in the reverse d irection and rewind the film thereon. It 1s prevented rom doing this by a roller friction brake fastened to the winding key 18 which is provided to operate on the spool 7. When the key is pulled out of engagement with the spool 7 the spring will operate to turn the spool 6 in the reverse 'direction, and wind the film 10 back thereon and draw it ofi' the spool 7 In this manner, the film can be entirely rewound on the spool 6 'after every exposure and a new adjustment of the lens front can bemade to put it in focus, after which the film 'can be wound forward on the spool 7 for a fresh exposure, the film being wound farther for each new exposure than for the preceding one. v

On two opposite sides of the rectangular opening 1Q, I provide the doors 14 and 15 close the which are turned in the position shown in Fig. 1 to uncover the back of the focusing screen 13. Surrounding focusing4 hood 16, whichcan be folded down into the back of 'the camera over the doors 14 and 15, or which can be extended as shown in Fig. 1 for the purpose of excluding the'light rays from the focusing screen 13 and forming a hood around it. J

lVith the focusing hood 16 and the doors 11' and 15 in the position shown in Fig. .1, the image can be observed on the focusing screen and the lens of the -camera can easily opening 12, and

be put in focus, after which the film can 'be drawn forward to its proper position, and the exposure can be made.

Thereafter the film can be drawn back away from the focusing screen, permitting the camera to be focused again, after which the film can again be drawn forward and the exposure made.

The spool 7 is rotated by means of the a draft roller mounted therein, a focusing screen between said rollers, means for winding a film from said supply roller to said draft roller across said focusing screen, a spring connected to said supply roller to automatically rewind the film from saidv draft roller back to said supply roller.

2. A camera having a supply roller and a draft roller mounted therein, a focusing screen between said rollers, means for winding a film from said supply roller to said draft roller across said focuslng screen, a

spring connected to said su ply roller to automatically rewind the fi m from said draft roller back to said su ply roller, while maintaining engagement tiierewith and allowing it to be drawn forward a ain for successive exposures, said means eing capable of extending past said 'focusing screen without intercepting the image therefrom.

3. A supply roller having a film wound thereon, a draft roller to which said film can be drawn, a focusing screen between said rollers, means for connecting the film while on the supply roller with said draft roller, said means beingattached to the end of said film and extending across the screen without intercepting the 1mage thereon.

4. A camera havlng a supply roller and a draft roller mounted therem, a focusing screen between said rollers, means on said draft roller for moving a film from said supply roller to said draft roller across said focusing screen, said means being adapted to allow the film to be moved back in the reverse direction past said focusing screen to said supply roler, and a coil spring attached to said supply roller, said coil spring being adapted to rewind said film on said supply roller.

In testimony whereof I afiix my signature.
